To all whom fit ma'y concern:

Be it known that I, WALTER zen of the United States,:residing at apolis,

Gox, a. citi- Indianin the county of Marion andState of Indiana, have "invented certain new and useful Improvements in'Cooling Systems, of

which the following .is

My said invention relates to a 7 system and it is an object thereof :to

a closed tank system which can be usedyfor all sorts of refrigerating work at high temperatures, .e. g. from about/ a specification.

coolinjg provide Fahrenheit to any required temperaturea'bove :zero.

' 1 In the drawings reference character 10 indicates the frame work of a box or tank or other container or compartment which is to be cooled. This container may character as is used in creameries,

be of such a butcher boxes, serum boxes, candy factories, ice

cream plants, milk distributors,

or any other place where objects or materials are subjected to cooling operations.

Within the container '1 have shown a group of closed tanks 11. In the present embodiment of the invention these tanks are four in number but it will be understood that any desirable number may be used without changing the character of the invention. The tanks are supported, preferably adjacent the upper corners of the container,

angle irons 12 .or by any other devices suitable to the situation, the angle irons 1n thls instance being shown as supported by brackets 13. 7

Above the tanks is a coil 14 connected to a supply header 15, this coil being y or posts 13 which support 12 on which the tanks rest.

carried angle irons 16 supported by the brackets the angle irons As indicated at 17 the coil 14 leads into a tank 11 and in the present instance 18 to the adjacent this tank is connected at tank 11 from the other end of whicha pipe leads which pipe connects at 19 to a return header 20.

A pipe to a brine balance tank 22 such as monly used in refrigerating plants 21 leads from the return header is com-' of large size. Alternatively the pipe 21 may be con- 1 nested to a gravity system if preferred.

.In the operation of my device the system s operated by any ofthe various types of brine coolers used in the trade, this brine cooler being connected to the :supplyphe'ader .15 and the return header 20 (or the tank 22) in usual manner. The cooling fluid from the brine cooler enters through the sup-ply header and the pipe pipe 18 to through 17 to the first 'tank 11 and the second tank, thence by way of pipe 1-9 to thereturn header. -20, thence to suction of brine pump 'During the entire circulation "and there .1

This possibility of operating the system efiiciently while a few hours reduces the cost of operaonly tion by 25 open tank running the brine cooler to 30 per cent below that of the and coilsystem. In addition to and passes through coil 14 odors from the i.

The system of baffles for control of the air. can be arranged for either central upward passage of the Warm air or central down- Ward passage of the cold air, as Will be understood by those skilled in the art. The coils 14 may be increased in number or may be omitted according to the Work to be done. The tanks may be changed in size and shape and many other changes may be made as will be obvious to those skilled in the art all Without departing from the spirit of the invention, the true scope of which is indicated in the appended claims.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:

1. A refrigerating system comprising a closed refrigerating compartment, a coil supported in an upper corner of said compartment, connections from the ends of the coil to the source of sup 31y, hold-over tanks or brine cylinders interposed in series with forth.

said coil adapted to contain a supply of cooling brine for maintaining the temperature approxin'iately uniform during intervals of inactivity of the system, substantially as set forth.

2. A refrigerating system comprising a closed refrigerating cormoartment a plurality of coils supported in upper corners of said compartment said coils being connected in series, a header connecting one coil to a source of refrigerant and another header leading back from another coil to said source of refrigerant, closed hold-over tanks or brine cylinders associated with said coils adapted to contain a supply of cooling brine for maintaining the temperature approximately uniform during intervals of inactivity of the system, and a brine balance tank in communication with the connection between a pair of coils, substantially as set WALTER ooX.
